Description

Technical Field

[0001] The utility model relates to a waterproof and moisture-proof structure, in particular to a waterproof and moisture-proof structure of a concrete basement top plate. Background Art

[0002] The basement roof refers to the top structure inside the basement, also known as the basement ceiling. It is usually made of building materials such as concrete, steel or wood. It is used to support the weight of the above-ground floors and protect the internal facilities of the basement. The basement roof is one of the important structures inside the basement. It has load-bearing, heat insulation, sound insulation, waterproof and moisture-proof and decorative functions, providing basic structural support and a good indoor environment for the basement.

[0003] During the actual construction and use process, the basement ceiling is very prone to moisture and leakage. Since the ceiling is built during the construction of the building, it is difficult to replace it later. Therefore, once moisture and leakage occur, it will cause great inconvenience to the users. Most of the current basement ceilings are waterproof and moisture-proof with the help of built-in water-stop steel plates or expansion strips at the connection gaps. However, due to the simple structure, the waterproof and moisture-proof effect is average. When moisture enters the interior, it cannot be effectively intercepted, resulting in moisture continuing to penetrate downward and causing dripping, which results in a very poor living experience. Utility Model Content

[0004] The purpose of the utility model is to provide a concrete basement roof waterproof and moisture-proof structure to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a concrete basement roof waterproof and moisture-proof structure, comprising two concrete roof panels, one side wall of the concrete roof panels being provided with a butt joint groove, the other side wall of the concrete roof panels being provided with a butt joint protrusion, the surface of the butt joint protrusion being fixedly connected to an expansion strip, the top surfaces of the two concrete roof panels being sequentially paved with a roll waterproof layer, a concrete rigid protective layer, and a polyurethane waterproof coating layer;

[0006] An expansion convex block is embedded between the docking groove and the top of the docking protrusion, a water delivery half pipe is embedded between the docking groove and the bottom of the docking protrusion, and a concrete filling strip is fixedly provided on the inner wall of the water delivery half pipe.

[0007] As a preferred technical solution of the present invention, two slots are provided on one side wall and the other side wall of the concrete top plate, and a water-stop steel plate is inserted between the two opposite slots.

[0008] As a preferred technical solution of the present invention, the shape of the docking groove matches the shape of the docking protrusion, and the expansion strip is placed between the docking groove and the docking protrusion.

[0009] As a preferred technical solution of the present invention, the two adjacent water-stop steel plates are respectively placed on the top and bottom of the expansion strip.

[0010] As a preferred technical solution of the present invention, the upper surface of the expansion protrusion is in contact with the bottom surface of the polyurethane waterproof coating layer.

[0011] As a preferred technical solution of the present invention, the top surface of the concrete filling strip is V-shaped and recessed, and a diversion gap is provided between the two side walls of the concrete filling strip and the inner wall of the water delivery half pipe.

[0012] As a preferred technical solution of the present invention, a water delivery gap is provided between the bottom surface of the concrete filling strip and the inner wall of the water delivery half pipe.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model can quickly connect two concrete top plates by setting docking grooves and docking protrusions, and the connection has many folds, which increases the water penetration path, thereby delaying water penetration and playing a certain water-blocking role. The expansion strip provided between the docking groove and the docking protrusion can expand when exposed to water. Under long-term use, the gap between the two concrete top plates is further filled, the gap size is reduced, and thus water ingress is reduced. The water-stop steel plates inserted at the top and bottom of the expansion strip form a horizontal water-blocking structure in the gap, reducing the downward penetration of water and playing a better waterproof and moisture-proof role.

[0015] 2. The utility model provides expansion protrusions at the connection between the two concrete top plates, which can first expand when exposed to water, thereby forming a bulge, partially lifting the multiple waterproof layers on the top, creating a slight bulge. In this way, the multiple waterproof layers locally form a "diversion platform" structure, which diverts moisture that may enter the connection gap here to both sides, further reducing the probability of entering the connection gap. The water delivery half-pipe embedded between the two concrete top plates and the concrete filling strips provided therein can intercept the downwardly penetrating moisture and collect it in the V-shaped depression of the concrete filling strip, increasing the difficulty of flowing to both sides. When the amount of water is large, it will flow along the diversion gap and converge into the water delivery gap of the water delivery half-pipe, thereby realizing the interception and transmission of moisture in the concrete top plate, and preventing the moisture from completely penetrating the top plate and causing dripping or soaking.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The utility model provides a technical solution for a waterproof and moisture-proof structure of a concrete basement roof:

[0023] Example 1:

[0024] according to Figure 1 、 Figure 2 and Figure 3 、 Figure 4 As shown, a concrete basement roof waterproof and moisture-proof structure includes two concrete roof panels 1. One side wall of the concrete roof panel 1 is provided with a docking groove 3, and the other side wall of the concrete roof panel 1 is provided with a docking protrusion 7. An expansion strip 8 is fixedly connected to the surface of the docking protrusion 7. The expansion strip 8 is made of water-swelling rubber and can perfectly fill the gap between the docking groove 3 and the docking protrusion 7, ensuring that the two are fully fitted after docking. The top surfaces of the two concrete roof panels 1 are sequentially covered with a roll waterproof layer 2, a concrete rigid protective layer 9, and a polyurethane waterproof coating layer 10;

[0025] Two slots 5 are provided on one side wall and the other side wall of the concrete top plate 1, and a waterstop steel plate 11 is inserted between the two opposite slots 5. The waterstop steel plate 11 is inserted horizontally to extend the path of the connection, thereby extending the water penetration path and reducing the water penetration speed and probability. The shape of the docking groove 3 matches the shape of the docking protrusion 7, and the expansion strip 8 is placed between the docking groove 3 and the docking protrusion 7. The two adjacent waterstop steel plates 11 are respectively placed at the top and bottom of the expansion strip 8.

[0026] During specific use, the utility model provides a waterproof and moisture-proof structure for a concrete basement roof. The operator can connect the two concrete roof plates 1 together with the help of the docking groove 3 and the docking protrusion 7, and place the expansion strip 8 between the two concrete roof plates 1. In subsequent long-term use, water or moisture enters the connection and is absorbed and expanded by the expansion strip 8, so that the two concrete roof plates 1 are more closely fitted together and the gap is filled. After the concrete roof plates 1 are connected and assembled, the polyurethane waterproof coating layer 10, the concrete rigid protective layer 9 and the rolled waterproof layer 2 can be laid on top layer by layer to play a water-proof barrier role towards the water surface and avoid moisture penetration. The two horizontally inserted water-stop steel plates 11 will form a horizontal barrier between the connection of the two concrete roof plates 1, further preventing moisture from penetrating downward.

[0027] Example 2:

[0028] Based on the first embodiment, Figure 1 、 Figure 2 and Figure 3 、 Figure 4 As shown, an expansion protrusion 4 is embedded between the docking groove 3 and the top of the docking protrusion 7. The expansion protrusion 4 is also made of water-swelling rubber and can expand after encountering water. Since there is no hard cover on the top, the top is slightly raised, and the multiple waterproof layers on the upper layer are slightly lifted up locally. In this way, the waterproof layer is in the local connection gap and presents a "waterproof platform" shape. The water flowing through this place is diverted to both sides to avoid seeping down along the connection gap. A water delivery half pipe 6 is embedded between the docking groove 3 and the bottom of the docking protrusion 7, and a concrete filling strip 13 is fixed on the inner wall of the water delivery half pipe 6;

[0029] The upper surface of the expansion protrusion 4 is in contact with the bottom surface of the polyurethane waterproof coating layer 10, and the top surface of the concrete filling strip 13 is V-shaped and concave. In this way, the small amount of moisture that first enters the top surface of the concrete filling strip 13 is not enough to continue to penetrate and spread to both sides, which has a certain effect of preventing moisture from penetrating and spreading. When the amount of water is large, it will spread from both sides and then enter the diversion gap 14. A diversion gap 14 is provided between the two side walls of the concrete filling strip 13 and the inner wall of the water delivery half pipe 6, and a water delivery gap 12 is provided between the bottom surface of the concrete filling strip 13 and the inner wall of the water delivery half pipe 6. The moisture entering the water delivery gap 12 will be transmitted under the transmission conditions of the water delivery half pipe 6 to avoid further downward penetration, thereby avoiding dripping of the basement roof and protecting the plate body. During construction, the water delivery half pipe 6 can be led out to the drainage area, so that the water that penetrates the roof can be intercepted and transmitted.

[0030] In specific use, the utility model provides a waterproof and moisture-proof structure for a concrete basement roof. After the concrete roof 1 is assembled and used for a long time, a small amount of moisture slowly penetrates into the connection between the two concrete roofs 1. The moisture first enters from the top and encounters the expansion protrusion 4. The expansion protrusion 4 is made of water-expanding rubber, which will expand and bulge, causing multiple waterproof layers placed on the top to be partially lifted up. In this way, the multiple waterproof layers at the connection are slightly bulged locally, forming a "diversion platform" structure, which guides the moisture that may enter the connection gap here to both sides. Flow, further reducing the probability of entering the connection gap. If some moisture still enters the connection gap between the two concrete top plates 1, the moisture will continue to penetrate downward and enter the top of the concrete filling strip 13 at the connection. The top surface of the concrete filling strip 13 is V-shaped and concave, making it difficult for the moisture to flow outward. However, when the amount of moisture increases, it will continue to penetrate to both sides and enter the diversion gap 14, and then converge into the water delivery gap 12 along the water delivery half pipe 6. In this way, the infiltrated moisture can be dredged along the long strip of water delivery gap 12 to avoid direct downward penetration.
